Specification of Letters Patent. Patentetll June 20, 1922,

Application filed. December 16, 1920. Serial No. 431,172.

To all to 7mm. it may concern Be it known that 1, N10 KRUMP, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Suspended Two-Rail Tracks, of which the following, when taken in chine and other shops where material on which work is being done is required to be transferred from one machine to another, or others; and to obtain a track which is not liable to break down, get out of order, or become clogged in a way to require any considerable effort to maintain it in constant use. I

In the drawing referred to Fig. 1 is aside elevation of a track and carriage embodying this invention.

Fig. 2 is a vertical section, on line 2-2 of Fig. 1, viewed as indicated by arrows.

Fig. 3 is a vertical section of a supporting beam, of the rails of a track embodying the invention, and ofv one side of a carriage forming an element of the invention; the other side of said carriage and some of the elements of the track being shown in end elevation.

Fig. 4 is a vertical section on' line i-et of Fig. 5, viewed as indicated by arrows.

Fig. 5 is a vertical section on line 5-5 of Fig. 4, viewed as indicated by arrows.

Fig. 6 is aside elevation'of an inverted T shaped member forming an element of the carriage member of the invention.

And Fig. 7 an end elevation of said in'-' verted T shaped member.

A reference character applied to designate a given part indicates said part throughout the several figures of the drawing, wherever the same appears.

The two rail track embodying the invention is ordinarily suspended from heavy beams, A, which are usually secured to the under side of floor joists of a shop or other building where the track and carriages are tobe installed. B represents a bolt which is illustrated as extending vertically through beam A, said bolt being provided with the eyelet b at its lower end, and screw threaded at its upper end, with the washer C and nut C thereon. D represents an inverted U shaped bolt which is provided with the screw threads (Z, (Z, at the lower ends thereof. E, 6, represent nuts which are provided with internal screw threads corresponding with the screw threads (Z, and fitting thereto. F represents a rail chair, which is provided on the edges of the upper face thereof with longitudinally extending flanges f, 7". G, G respectively represent rails, which are provided with bases 9, g, vertical flanges g, g, and wheel treads 9 To properly position the rails G, G, in the chairs F, F, of the installation, a portion of bases g, g, of the rails is cut therefrom, as on lines g 9 Figures 3 and 5. H represents a locking member which, on its under side, 71 fits to and rests on the upper faces of bases g, g, of rails G, G, on the inner side of the vertical flanges y, g, of said rails. Said member H is also provided with apertures corresponding in diameter with the diameter of the U-shaped member D, in which said member fits and extends through. The rails G, G, are supported at pre-determined points by being placed in the rail chairs F, F. Said chairs and members H, are threaded on the U-shaped members D, D, with the nuts E, e, turned firmly to place so that said chairs F, F, are supported on said nuts E, E, and said members H, H, are forced firmly down on to members 9, g, by nuts 6, 6, thus holding rails G, G, rigidly in place in said chairs. By this construction the rails Gr, G, are not suspended, but are mounted on the rail chairs, said chairs being mounted on the nuts E, E, and said U-shaped members D, D, being suspended from the bolts B, B, by being passed through the eyelets b, b, in said bolts B, B.

I, represents a U-shaped member forming a supporting element of the carriage which co acts with the track constructed as above set forth. Member I is made in two parts vwhich are rigidly held together by bolts. 1', 2',

The bumper members are, respectively, two part, and are provided with grooves on .the meeting faces of the parts, which register toform vertical apertures having two diameters, when bolts 13, i, are in place to join the two parts of the U-shapedmembers 1,1, together, and J, Fig; 3.,represe11ts the said a erture of larger diameter.

. wheels, k, is, being the flanges thereof. Wheels K, K, are rotatably' mounted on axles L, L, at the upper ends of the le s of U shaped supporting member I; and Z, represent nuts on said axles which secure said axles rigidly in place. j

M represents an inverted T shaped member, the vertical element whereof is circular and of two diameters, asatm, m, Figs. 6 and 7 Part m of said vertical element fits in the part J of the aperture-in supporting memher I, and part on fits in the part of said Part m is aperture of. smaller diameter. rectangular and provided with apertures m m N represents a carriage bar, duplicates whereof are rigidly secured to part m of membersM by bolts 02 andenuts n N, Figs. 1 and 2, represents a two part rectangular member, 7 which are provided with grooves on adjacent sides, adapted to register and form an aperture of two diameters when said members are secured in place between the bars N, N, (as by bolts n, n), the part of said aperture of larger diameter belng represented and designated as O.

P represents an eye bolt, the upper end whereof, p is of larger diameter than thecircular part p thereof, 17 represents the eyelet at the lower end of-bolt P, from which eyelet, by suitable chain or cable, the material to be transferred from one place to another by means of the carriage last above described. The part p of bolt P fits in part 0 of the aperture which is formed through the two part member N by the grooves on adjacent faces of said member N. And the part 12 of said bolt fits the remainder of said aperture to turn loosely therein.

To assemble the several parts to form the carriage the circular parts m, m are placed in the grooves in the bufier element I of the supporting member I; and said buffer elements are firmly secured together by bolts or rivets i, z". The bars N, N, are rigidly secured to part m of member M, by bolts or part of respectively represent flanged car.

rivets n, m The eye bolt P is placed in the I grooves on adjacent sides of two part member -N.", said two part member is placed between the bars N, N, and rigidly secured in place by bolts or rivets n, 'm.' When thus assembled the U shaped supporting members I turn freely on the parts m,..m' of. the inverted Tshaped member M, when said carriage is moved along onthe hereinbefore two rail track, and the wheels'K, K, are on a curved portion of said track; as in turning corners, traveling over switches, or along curves'and bends.

I claim;

1. In. a suspended tworail track, an inverted U-shaped bolt provided with screw threads on the ends thereof, and a rail chair, in combination with rails resting on said chair, a locking member on the bases of said rails, said chair and said locking member respectively provided with apertures corre ,s'ponding in diameter with the diameter of said ends of said U shaped bolt, and nuts fitting on and engaging with said screw threads, the lower ones of said nuts adapted to be forced upward against the under side of said chair and the upper ones adapted to be forced downward on to the upper side of said locking member.

2. A vertically mounted eye-bolt, an inverted U-shaped bolt suspended on said eyebolt, and rovided with external screw threads on t' e ends thereof, a rail chair and rails respectively provided with bases rest- ,ing on said chair, in combination with a lockin -member arranged to rest on adjacent si es of said bases, said locking member and said chair respectively provided with apertures corresponding with and fitting on said screw threaded ends, and nuts provided with internal screw threads engageable with the screw threads on said'ends, the lower ones of said nuts adapted to be turned against the lower side of said chairand the upper ones of said nuts adapted to be turned down on to the upper side of said locking member, to rigidly hold said rails in said. chair and 'to hold said chair in an adjusted position on said inverted U-shaped bolt.
